Described herein are devices, systems, and methods relating to making individuals comfortable when in contact with surfaces (e.g., seats and beds) including preventing pressure injuries on subjects. In embodiments, disclosed herein are pressure injury prevention systems comprising actuator assemblies that can simultaneously provide immersion and offloading of pressure while allowing a subject to retain balance. In other embodiments, moisture control devices and/or sensing networks can be used in conjunction with said actuator assemblies to prevent pressure injuries in a subject in need thereof. In embodiments, also described herein are computing devices and applications that alert a manual intervention or trigger an automated intervention between the individual and the intervention surface based on a risk determination. Such interventions can send instructions to the system to relieve pressure and/or moisture at one or more interface locations on the interface surface between the system and a subject according to a set of rules based on a predetermined profile, data collected continuously in real time, or both.

A reconfigurable apparatus for sitting and having a seat mounted on a frame and movable under the weight of a sitting user. As an incident of the user sitting, resistance to movement of a back rest component is increased a predetermined amount based upon the user's weight. A manually operable subassembly allows the increased resistance to be changed from the predetermined amount with the user sitting on the seat.

An automatically adjusting comfort method includes measuring pressure applied by a user via a pressure-sensor array, determining a pressure profile based on measurements from the pressure-sensor array, comparing the pressure profile to a first limit, determining a cumulative pressure profile over a predetermined duration, comparing the cumulative pressure profile to a second limit, and adjusting one or more of a plurality of adjusting mechanisms configured to alter the pressure profile for increased comfort of the user when the pressure profile exceeds the first limit or the second limit. An automatically adjusting comfort system includes a pressure-sensor array communicatively coupled to a controller for determining a cumulative pressure profile over time, and a plurality of adjusting mechanisms configured to alter the pressure profile to increase a user's comfort, wherein the controller automatically adjusts one or more of the plurality of adjusting mechanisms based on the cumulative pressure profile.

A lounge chair includes a frame having a pair of longitudinal sides and a pair of lateral sides extending between the pair of longitudinal sides and defining a space therebetween. The lounge chair further includes a seat portion supported on the frame and arranged inside the space. The seat portion provides a surface for a user to lie down. The seat portion defines a first opening arranged proximate to a first lateral side of the pair of lateral sides and extending through the seat portion. Also, one of the frame or the seat portion defines a second opening and a third opening arranged facing each other. The first opening receives a head and a neck of the user and the second and third openings receive arms of the user when the user is lying in a face-down position on the seat portion.

A vehicle seating assembly includes a seat base that has a first heating element. A seat back has a second heating element. A sensor is coupled to the seat base and is configured to obtain a weight data. A user-interface assembly is operably coupled to the first and second heating elements. A controller is in communication with the sensor to receive the weight data. The controller is configured to control the first and second heating elements in response to the weight data.

A system and method establishing control of affordances at a workstation. The method includes the steps of storing affordance preferences in a database for a plurality of portable affordance settings that may be present at a workstation, detecting a subset of affordances present within a first zone associated with the workstation, for each detected affordance in the subset, identifying an affordance setting in the database indicating a user preference, and automatically controlling settings of at least each of the detected affordances in the subset to match the user preferences for the detected affordances.

Disclosed herein is a chair that includes a backrest portion, a seat portion coupled with the backrest portion, a column portion coupled with the seat portion, a linkage coupled with the backrest portion, a leaf spring in direct contact with the linkage, an arc-shaped toothed structure fixed translationally relative to the column portion, and a different toothed structure in contact with the arc-shaped toothed structure. The chair is also configured such that when a weight is applied to the seat portion, a fulcrum point of the leaf spring moves as the different toothed structure moves along the arc-shaped toothed structure to thereby shorten a working length of the leaf spring and provide an increased resistance to tilting of the backrest portion relative to the column portion. A process for assembling the chair and a weight-based tilt-resistance assembly for use with the chair are also described herein.

An improved bed and method of forming with the required profile and localised support for a user by the improved bed at various sections of the bed including shoulder (A), lumbar (B) hip and lower body (C) such as by the mattress (15) having selected forms or voids a Shoulder Pressure Attenuation Area (SPAAM) a Lumbar Pressure Attenuation Area (LPAAM) a Hip Pressure Attenuation Area (HPAAM) and the base (26) having a Shoulder Pressure Attenuation Area (SPAAB) a Lumbar Pressure Attenuation Area (LPAAB) a Hip Pressure Attenuation Area (HPAAB) locatable at different locations along the longitudinal extension of the bed (32,42,52) with a Shoulder Pressure variation means (31) a Lumbar Pressure variation means (41) and a Hip Pressure variation means (51) comprising adjustable slats driven by electric motors.

A support surface including a cutout on a bottom surface of the support surface. The cutout, which can include a plurality of cutouts, provides a controlled structural collapse of the support surface by varying a stiffness in a cross-section. That is, the area in which the cutouts are positioned collapses more easily than the surrounding area of the support structure, thus making the area with the cutouts perceived as being softer. The cutouts can reduce the peak pressures on the portion of the user's body (for example, the user's ischial tuberosities) that is positioned over the cutouts. The support surface can also include a low-friction interface extending across a top surface of the support surface.

Surgical robotic systems including a user console for controlling a robotic arm or a surgical robotic tool are described. The user console includes components designed to automatically adapt to anthropometric characteristics of a user. A processor of the surgical robotic system is configured to receive anthropometric inputs corresponding to the anthropometric characteristics and to generate an initial console configuration of the user console based on the inputs using a machine learning model. Actuators automatically adjust a seat, a display, or one or more pedals of the user console to the initial console configuration. The initial console configuration establishes a comfortable relative position between the user and the console components. Other embodiments are described and claimed.
